Sorry if this has been asked before, but when we develop a roll of film and print it at a standard consumer print lab, using say normal Kodak Royal or whatever paper, what sort of resolution does it give? For 4R,5R,8R?

what do you need the info for? if you want to know the paper sizes, 4R is 4 by 6 inches, 5R is 5 by 7 and 8R is 8 by 10.

it depends on the machine used...
you can go ask the shop and they might know... if not look at what machine they use and search for the specs on the internet...
the fuji frontier 350 that FDI shops use prints at 300dpi if you really must know...

Thanks for replies. Just to compare resolution with those that home photo printers (low or medium end).
Also to set scanner resolution to scan them in. Am I correct in saying if print is only 300dpi, no point scanning it any res. beyond that?

If the print contains 300DPI of information, you would need to scan at at least twice the "freqeuncy" (nyquist freqency) to be able to recreate the original print. So, you should scan at 600DPI if you want to be able to recreate the original pic at the original size.

Tks. That is still (at 600dpi) much lower than resolutions supported by new flat scanners (3200 etc). Interesting..
What about printer manf. that advertise 4800dpi and 5400dpi? Anyone knows if that's just spin or got some real value?

Always take the lower of the 2 figures given (e.g. 2400x1200 dpi) as the true resolution of the scanner. Also, beware of interpolation figures.
